    Frequently asked questions

    Is there a limit on how many PDFs I can merge?

    There is no fixed limit. Because merging happens in your browser, the practical limit is your device memory. Most phones handle a few hundred pages easily.

    Will merging reduce the quality of my PDF?

    No. Pages are copied as they are, so text stays sharp and images keep their original quality.

    Can I merge password-protected PDFs?

    Encrypted PDFs must be unlocked first. Open them in your PDF reader with the password and save an unprotected copy, then merge.
